NVIDIA hasn't said much about the architectural details about its latest Tegra SoC, other than to confirm that it features 192 CUDA cores. Since we already know Tegra K1 is based on NVIDIA's Kepler GPU architecture, and a single Kepler SMX features 192 CUDA cores, we know that K1 uses a single Kepler SMX.

With K1, NVIDIA ditches the GeForce ULP GPU core that was present in the previous four generations of Tegra and moves mobile onto the same roadmap as the desktop/notebook GeForce. NVIDIA used the slide below that seems to imply convergence between the Tegra and GeForce architectures going forward, even beyond Kepler.

We'll be updating this post with more details as NVIDIA reveals them.

Tegra K1 will be available in quad-core Cortex A15 (+1 shadow Cortex A15 core) and dual-core Denver (64-bit ARMv8) versions. The Cortex A15 version will be available in 1H 2014, the Denver version will show up in the second half of 2014.

Nvidia doesn't really ever show "die shots" of their Tegra line. Everything they show off is doctored to the point where it stops being a die shot and becomes an "artist's representation."

Here, for instance, they've copy-pasted some terrible little thumbnail of a "core" to try to portray the (stupid) idea that it's a "192 core processor."

If you can't tell, I'm rather annoyed at Nvidia's decision to alter their die shots so much. Even their flagship GPU die shots are photoshopped worse than adult industry workers. It's been this way since Fermi showed up.

Their Project Denver mockup (http://bit.ly/1d9zCMR) was a chopped up and regurgitated GF100. It's incredibly misleading at best, and false advertising at worst. Nvidia's not alone in this; AMD has done similar things as well (e.g. a supposed Cayman die shot, where a Barcelona die was superimposed on R770), but not nearly to the same extent. Intel also makes heavily-shopped die representations. Nvidia’s by far the worst, though. You’d be best off passing off Nvidia’s official die shots as being fake, because they honestly are.Reply

You only need to look at the fifth CPU core to see that it's a shrunken down image of the other cores. In reality it's either an A7 for the low-power operation, or the fifth core is an A15 and would be roughly the same size at the other A15s.Reply
